Mum: It’s called iTunesU. It’s where you can get books and information into the phone.

Son: No, what’s it a picture of?

Mum: It’s a hat. It’s called a ‘mortar board‘. It’s what people wear when they graduate from University. It’s our Graduation Day today! There will be lots of people at my work wearing funny hats!

Son: What’s ‘Graduation Day’?

Mum: It’s a day when we celebrate that people have finished their courses.

Son: What’s a ‘course’?

Mum: It’s when people decide to learn about certain things, and gather lots of information. Then they write about what they’ve learned in books and things. And today we’re celebrating because they’ve learned what they wanted to learn to make them better at doing things. Some of them will get prizes too for doing really well at certain things.

Son: What prizes will they get?

Mum: I’m not sure.

Son: How many people is there?

Mum: I think there are about 20 in our part of the day.

Son: Well… [looks around] You can give them some of my shells from Crete. I’ll give you three and you’ll have to find something else at your work for the rest of the people.
